The first is that there are two different kinds of heat value (as some of you know). High heat value and low heat value. ... If you aknowledge that the products leave the engine as gases, you get the "low heat value."...

I have to say to this point that I've been assuming a simple bomb calorimeter type measurement of the BTU of gasoline. I am struggling to understand how using an intermediate value makes any sense though. If the engine (or powerplant) releases hot gasses (or even liquid that is slightly above room temperature) it is releasing energy that it might otherwise be using.
One doesn't get to apply a handicap because the discharge happens to be in gaseous state, I don't get that at all.
